Assessment of undiscovered oil and gas resources of the Illinois Basin, 2007 [ More info] We estimated a mean of 214 million barrels of oil, 4.65 trillion cubic feet of natural gas, and 24 million barrels of natural gas liquids in this area using a geology-based assessment methodology.
Biomarker Benchmarks: Reproductive and Endocrine Biomarkers in Largemouth Bass and Common Carp from United States Waters [ More info] Describes a national reconnaissance study of reproductive health in two species of fish across the US. More than 2,200 common carp and 650 largemouth bass were collected at 119 rivers and streams.
Earthquakes in the central United States, 1699-2010 [ More info] Poster includes GIS data for earthquake locations in this seismically active area.
Land-cover change research at the U.S. Geological Survey-assessing our nation's dynamic land surface [ More info] Estimates of change in major types of land use and land cover from 1973 to 2000 should help model potential future change as climate, population, public policy, and technology change.
Regional assessments of the Nation's water quality--Improved understanding of stream nutrient sources through enhanced modeling capabilities [ More info] Studies of the sources, transport, and fate of nutrients in the streams of six major regions of the conterminous United States.
